Description

Technical Field

[0001] The invention relates to the technical field of liquid height measuring equipment, in particular to a liquid level meter for real-time monitoring of liquid level. Background Art

[0002] A liquid level meter is a device used to measure and display the height of the liquid level in a container. It is widely used in various industrial and civil fields. There are many types of liquid level meters, each with its own unique working principle and application scenario. Among them, the ultrasonic level meter emits ultrasonic pulses, which are reflected back after encountering the measured liquid surface, received by the same sensor, and converted into electrical signals through piezoelectric crystals. By calculating the emission and reception time of the sound wave, the distance from the sensor to the surface of the measured liquid can be calculated, thereby realizing the measurement of the liquid level.

[0003] The prior art has the following deficiencies: the “ultrasonic liquid level meter” in the prior art with publication number CN214372791U “includes a receiving seat, a liquid level meter body and a sealing cover assembly, wherein the receiving seat is suitable for being installed on a carrier, the receiving seat has a receiving cavity, the upper end of the receiving cavity is open to form an opening, and the bottom wall of the receiving cavity is provided with a threaded hole; the liquid level meter body is penetrated in the receiving cavity from top to bottom, the liquid level meter body has a wiring terminal, a detection terminal and a threaded section located between the wiring terminal and the detection terminal, the wiring terminal is located in the receiving cavity, the threaded section is threadedly matched with the threaded hole, and the detection terminal passes through the threaded hole; the sealing cover assembly is detachably connected to the receiving seat and seals the opening”.

[0004] The above structure adjusts the height of the detection end by rotating the level meter body, so that the blind area is far away from the highest liquid level, and its installation is simpler and more convenient. However, this structure does not improve the operating state of the ultrasonic level meter. Traditional ultrasonic level meters all adopt a fixed-point installation method, perpendicular to the liquid surface, but this installation method makes it impossible to change the monitoring position at will after installation, resulting in a single monitoring data with poor accuracy. If there is an inclined surface between the level meter and the liquid surface, it will affect the reflection of the ultrasonic wave, and the ultrasonic level meter lacks a protective structure and is easily damaged under polar temperatures. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a liquid level meter for real-time monitoring of the liquid level, which solves the current problems of being unable to flexibly change the monitoring position after installation and lack of protection in low temperature environments.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a liquid level meter for real-time monitoring of liquid level, comprising a mounting frame, a control panel, a signal receiver and a positioning bolt, wherein the control panel is arranged on the rear end face of the mounting frame, the signal receiver is arranged on the end face on the same side of the mounting frame, the positioning bolt is arranged on the inner side of the mounting frame, and a motor is arranged on the inner side of the mounting frame.

[0007] A heating machine is also arranged at the rear end of the mounting frame, a driving gear is arranged at the upper end of the motor, an adjusting frame is arranged at one side of the driving gear, and an insulation box is arranged at the side of the adjusting frame.

[0008] The driving gear also includes an adjusting gear and a supporting column. The tooth groove of the adjusting gear is meshed with the driving gear, and the supporting column is fixedly connected to the upper end surface of the adjusting gear.

[0009] In some of the embodiments, the driving gear is in active connection with the motor, and a shaft structure is provided at the bottom of the adjusting gear, and is movably connected to the mounting frame through the shaft structure.

[0010] In some embodiments, the adjustment frame further includes an ultrasonic level meter probe and a rack. The ultrasonic level meter probe is plugged into the end of the adjustment frame away from the support column, and the rack is fixedly connected to the side end close to the ultrasonic level meter probe.

[0011] In some embodiments, the adjustment frame is in an overall strip-shaped structure, a hollow groove structure penetrating from top to bottom is provided in the middle thereof, and an end away from the ultrasonic level meter probe is fixedly connected to a support column.

[0012] In some embodiments, the thermal insulation box also includes a self-closing sealing cover, a linkage gear and a heat-conducting copper tube. The linkage gear establishes an active connection with the side end of the thermal insulation box, the self-closing sealing cover is inserted into the outer end face of the linkage gear, and the heat-conducting copper tube is fixedly installed on the inner wall end face of the thermal insulation box.

[0013] In some of the embodiments, the bottom and the upper end surface of the thermal insulation box are both provided with groove structures in the same direction, and the side end of the self-closing sealing cover is provided with a groove structure of the same shape.

[0014] In some of the embodiments, the heat-conducting copper tube passes through the side wall of the installation frame and establishes a movable connection with the heating machine through plugging.

[0015] In some of the embodiments, the signal receiver is connected to the motor and the ultrasonic level meter probe via external lines and is centrally controlled by a control panel.

[0016] In some of the embodiments, the upper ends of the driving gear and the adjusting gear are both provided with block-shaped support structures, and the connection points are both provided with shaft seat structures. The block-shaped support structures extend backward to the side walls of the mounting frame and establish a fixed connection relationship.

[0017] Compared with the prior art, the present invention provides a liquid level meter for real-time monitoring of liquid level:

[0018] A liquid level meter for real-time monitoring of liquid level height is provided. By setting a driving gear, an adjusting gear, an adjusting frame, a rack, an insulation box and a self-closing sealing cover, before using the device, the installation frame needs to be installed above the liquid to be monitored through a positioning bolt, and the operator controls the motor, the heating machine and the ultrasonic liquid level meter probe through a control panel. When water level monitoring is required, the motor drives the adjusting gear through the driving gear, and when the adjusting gear rotates, the supporting column is driven to rotate, and the adjusting frame is driven to rotate toward the outside of the installation frame, until the ultrasonic liquid level meter probe is located directly above the liquid surface, the water level is measured through the ultrasonic liquid level meter probe, and then the collected information is transmitted to the signal receiver and fed back to the control panel. When the temperature is low, the operator can control the motor to reverse after the ultrasonic liquid level meter probe is used to reset the adjusting frame. During the resetting process of the adjusting frame, the rack at the front end thereof generates friction with the linkage gear, and causes the linkage gear to rotate, and the linkage gear drives the self-closing sealing cover to close. At this time, the ultrasonic liquid level meter probe is inside the insulation box. At this time, the operator controls the heating machine to heat the heat-conducting copper tube, so that the temperature around the ultrasonic liquid level meter probe rises.

[0019] The above settings and processes can make the device have the following beneficial effects:

[0020] 1. Through the coordination of the adjustment frame, the adjustment gear and the driving gear, the ultrasonic level meter probe can flexibly adjust the monitoring position when monitoring the water level to prevent the slope position from failing to reflect the ultrasonic wave. In addition, the data collected by multi-point monitoring is more accurate than that of traditional fixed-point monitoring.

[0021] 2. Through the cooperation of the insulation box, linkage gear, self-closing sealing cover and heat-conducting copper tube, the ultrasonic level meter probe can be recovered when not in use and placed in the external protection structure, and can provide protection for the ultrasonic level meter probe at extremely low temperatures.

[0036] In this embodiment, the driving gear 7 establishes an active connection with the motor 6, and an axis structure is provided at the bottom of the adjusting gear 701, and the mounting frame 1 is movably connected through the axis structure; the adjusting frame 8 also includes an ultrasonic level meter probe 801 and a rack 802, the ultrasonic level meter probe 801 is plugged into the end of one side of the adjusting frame 8 away from the support column 702, and the rack 802 is fixedly connected to the side end close to the ultrasonic level meter probe 801.

[0037] Specifically, Figure 1 , Figure 3 , Figure 4 As shown, the adjusting gear 701 is supported to rotate by the shaft structure at the bottom, and the driving gear 7 serves as a driving structure to drive the adjusting gear 701 to rotate.

[0038] In this embodiment, the adjustment frame 8 is an overall strip-shaped structure, with a hollow groove structure running through the middle from top to bottom, and the end away from the ultrasonic level meter probe 801 is fixedly connected to the support column 702; the insulation box 9 also includes a self-closing sealing cover 901, a linkage gear 902 and a heat-conducting copper tube 903, and the linkage gear 902 establishes an active connection relationship with the side end of the insulation box 9, the self-closing sealing cover 901 is inserted into the outer end face of the linkage gear 902, and the heat-conducting copper tube 903 is fixedly installed on the inner wall end face of the insulation box 9.

[0039] Specifically, Figure 6 and Figure 7 As shown, when the adjustment frame 8 rotates outward, the side wall contacts the self-closing sealing cover 901, and the self-closing sealing cover 901 is opened through the contact between the rack 802 and the linkage gear 902. When the adjustment frame 8 is reset, the self-closing sealing cover 901 is closed by the reverse rotation of the linkage gear 902.

[0040] In this embodiment, the bottom and upper end surfaces of the insulation box 9 are both provided with groove structures in the same direction, and the side end of the self-closing sealing cover 901 is provided with a groove structure of the same shape; the heat-conducting copper tube 903 passes through the side wall of the installation frame 1 and establishes an active connection relationship with the heating machine 5 through plug-in.

[0041] Specifically, Figure 2 and Figure 5As shown, the grooves on the inner side of the insulation box 9 are consistent with the shapes of the adjustment frame 8 and the ultrasonic level meter probe 801, thereby ensuring that the adjustment frame 8 can quickly embed the ultrasonic level meter probe 801 into the insulation box 9.

The operator controls the motor 6, the heating machine 5 and the ultrasonic level meter probe 801 through the control panel 2. When water level monitoring is required, the motor 6 drives the adjusting gear 701 through the driving gear 7. When the adjusting gear 701 rotates, it drives the support column 702 to rotate, and at the same time drives the adjusting frame 8 to rotate toward the outside of the installation frame 1 until the ultrasonic level meter probe 801 is located directly above the liquid surface. The water level is measured by the ultrasonic level meter probe 801, and the collected information is then recorded. The signal is transmitted to the signal receiver 3 and fed back to the control panel 2. When the temperature is low, the operator can control the motor 6 to run in reverse after using the ultrasonic level meter probe 801 to reset the adjustment frame 8. During the resetting process of the adjustment frame 8, the rack 802 at its front end generates friction with the linkage gear 902, and causes the linkage gear 902 to rotate, and the linkage gear 902 drives the self-closing sealing cover 901 to close. At this time, the ultrasonic level meter probe 801 is inside the insulation box 9. At this time, the operator controls the heating machine 5 to heat the heat-conducting copper tube 903, so that the temperature around the ultrasonic level meter probe 801 rises.
